I tend to agree with you that as bare-knuckle politics goes this is not beyond the pale. On the other hand, it is way worse than what Ohio has done in that Ohio has five Democratic seats out of 15 all together. If you do the analysis that some people did upthread about if you only have 40% of the voters or something like that, that you can justify zero members of the minority party. This is not that bad in that analysis either.
I would also mention that cuccinelli goes through four arguments that he thinks are legitimate. On the surface, they all sound legitimate to me but I realize he is not an objective source. Even if his arguments are sound, the odds are the Virginia supreme Court will find a way to evade what Virginia law is regarding the enactment of constitutional amendments.
I wasn't explicit about what Ohio had done. They banned partisan gerrymandering, their Supreme Court ruled the maps unconstitutional, and the state legislature just ignored them. That's what's worse.
